Fig. 7 is aplan vie-W of the underside of the skate, showing extended and contracted positions'of heel andtoe plates. Fig. 8 is a front view of the skate. Fig. 9 is across-section on the line .r m of Fig. 7. Fig. l() is a perspective viewofthe front rubber, f5.

Like letters of reference indicate like parts.

The object of my invention is to make a rollenskate that shall beadjustable longitudinally, and in which the bearings shall have alimited side motion regulated by screws and rubber cushions,substantially as shown.

The skate is made of a front part, a, having a piece, a', integral withit, and a rear part, b, with a part or piece, b, integral with it. Saidparts are held together by an independent piece or bridge, ci, havingloops e2 at its ends, in which freely slide the parts a' Zi. Near thecenter ofthe piece c are prongs e, on Aeach side. which hold betweenthere a nut, e, fixed to the center of a shaft, d, on which are cutright and left hand screw threads. Said 'screw enters into the nuts c,fixed into and forming the end of the channel-like parts a. b', and liesor Works freely in the channel c. By turning said nut e, and the'rebythe screw d, the parts ab' will be moved to or from the nut e, and thusseparate or bring together the parts a l).

'lo the heel-plate b are cast, integral there- With, spurs or guards It,and slots for a strap, and to the toe`plate c are attached adjustablespurs g, which have a blade which slides in a channel, and a fixed boltwhich slides in a slot through the plate a, and to which is attached anut, g, by means of which each spur is secured in its place. Said spurshooi; inward, so that when set they will catch the sole of the boot,when pushed into itlongitudinally, and hold securely Without furthertrouble.

The standards or carriers f play on pins f which pass through lugs f,attached to the heel and toe plates. The carriers f have above ,the pinsfT horizontal plates j, integral with them, through which, near theirouter longitudinal edges, pass set-screws f8, against plates fifi, andsaid plates carry rubber blocks f3 f5, which press against the plates aand ZJ. Said rubber blocks yield to lateral pressure of the carriers f,and by means of the screws fS more or less resistance may be given saidparts.

That I claim is- 1. In airoller-skate, the combination ofthe parts a,@having attached to them parts a b', united `by a bridge-piece, ci, andadjustingscrews d, substantially as specified. 4

2. In a roller-skate, rthe combination of the parts a a I) 1)',withbridge-piece c3, having loops ci, and screws d, provided with nut e, andspurs e', substantially as specified.

3. In combination with the adjustable plates a b, bridge-piece c, screwsd, nut e, and spurs e', the spurs 71., and adjustable spurs g,substantially as specified.
